IMPROVEMENT IN COTTON-GINS.

Specification forming part of Letters Patent No. 220,854, dated October21, 1879; application filed August 2, 1879.

To all whom it may concern:

Be it known that I, JOHN F. MEANS, of Thomaston, in the county of Upsonand State of Georgia, have invented certain new and useful Improvementsin Cotton-Grins; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference-markedthereon.

Figure 1 of the drawings is a representation of a face of my cotton-gin,and Fig. 2 is a detail view of the same.

This invention relates to cottomgins; 'and it consists in theimprovements in the construction of the same hereinafter fullydescribed, and particularly pointed out in the claim.

Let A represent the base of a frame composed, essentially, of theuprights b, cross-bars c, and an elevated platform, d. The main rotaryand vertical shaft 0 carries a pulley-wheel, f, and a smaller horizontalshaft, g, which is journaled in the bearing-pieces h, and is providedwith a pulley-wheel, i.

J designates an endless belt, which passes round the wheel f and thehorizontal shaft 9.

' The devices for giving a proper tension to this belt are as follows:Two timbers are each secured t0 the platform and base of the frame, andthrough suitable guide-openings in the same the two side bars of asliding frame, 10,

are passed. This frame carries a short rotary roll or wheel, q, whichwhen the frame is moved in one direction, bears upon the belt, and hencegives the same the requisite tension.

In order to regulate the tension so that it shall be equal at all times,I suspend a weight upon one end of a rope, which is secured to thesliding frame, and thence passes over a roller or wheel, I. This latterroll or wheel is journaled between the inclined bars m, which aresecured at their lower ends to the base of the frame, and at their upperends to a projecting timber, n.

0 represents a frame upon the main vertical shaft, and this frame hasprojecting handles or bars, whereby the shaft may be worked either byhorse or man power.

What I claim is- In a cotton-gin, the combination of the sliding framep, carrying the roller q, with the vertical shaft 6, carrying the pulleyf, the shaft g, carrying the wheel 11, the endless belt J, the frame 1n,having roller 1, and the cord and weight, as shown and described, forthe purposes specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN FRANCIS MEANS.
